Using Django

Forms.py: I want to hide job_role field when user_type= admin selected in ‘is_superuser’ field

class CreateUserForm(HelperForm):
    USER_TYPE_CHOICES = (
        (False, 'Employee'),
        (True, 'Admin'),
    )
    first_name = forms.CharField(
        label="First Name",
        max_length=30,
        required=True,
        validators=[firstNameValidator]
    )
    last_name = forms.CharField(
        label="Last Name",
        max_length=30,
        required=True,
        validators=[lastNameValidator]
    )
    email = forms.EmailField(
        label="Email",
        required=True,
        validators=[emailValidator]
    )
    job_role = forms.ModelChoiceField(queryset=Group.objects.all())
    is_superuser = forms.ChoiceField(label='User Type', choices=USER_TYPE_CHOICES)
    is_active = forms.BooleanField(initial=False, required=False, widget=forms.HiddenInput())

    class Meta:
        model = User
        fields = ('first_name', 'last_name', 'username',
                  'email', 'is_superuser', 'job_role', 'is_active')

I am not aware of any facility within Django providing that feature. It would take a little bit of JavaScript embedded within your page to hide/show a field depending upon the value of a different field.

Are you referring to doing this in JavaScript in the browser to handle the hiding of a field? Or are you referring to how you need to handle the form once it has been submitted to Django?

If the former, it’s highly dependent upon whether or not you’re using a JavaScript library or framework to provide client-side UI enhancements, such as jQuery. We use jQuery where I work, so that’s what I’m most familiar with, but it might be a bit much if this is the only enhancement you’re looking to add to an otherwise plain form. (If the latter, then I would end up referring you to a variety of documentation addressing form handling.)
